Whole property protection.
Step S103, search whether picture corresponding to identification information be present in the buffer using identification information.
It should be noted that because identification information is to be generated according to the URL of picture, identification information is uniquely right with picture
Should, and searching whether picture corresponding to identification information be present in the buffer using identification information, needed when being and calculating loading webpage
The identification information for the picture to be shown, identification information corresponding with the picture in caching are contrasted to search.In above-mentioned caching
Picture corresponding to identification information be identification information that the picture generates in caching according to the URL of the picture, and by the figure
The identification information of piece is also marked on the picture.The identification information of picture shown will be needed when will load webpage, and in caching
Identification information corresponding to picture is contrasted to search, if finding the identification information of the picture with needing to show during loading webpage
Identification information corresponding to picture in identical caching, the then picture that load needs to show during webpage are present in caching, if
Identification information corresponding with the picture in the identification information identical caching for the picture for needing to show during loading webpage is not found,
The picture that then load needs to show during webpage is not existed in caching.
For example, existing picture 1 in caching, and the picture 1, with the addition of identification information BZ1, the BZ1 is according to picture
1 URL generations.User is when browsing webpage, it is necessary to which Load Image 2 and picture 3, picture 2 is generated according to the URL of picture 2
Identification information is BZ1, according to the URL of picture 3 generate picture 3 identification information be BZ2, then by the identification information BZ1 of picture 2 with
And the identification information BZ2 of picture 3 and picture in caching identification information are contrasted, the result of contrast is the mark letter of picture 2
Breath is identical with the identification information of picture 1 in caching, and does not find the identification information BZ2 identicals with picture 3 in the buffer
Identification information, then it can determine whether as picture 2 is present in caching, and picture 3 is not cached also.
By above-mentioned technological means, realize needs whether the picture shown is present in caching when judging to load webpage
In.
Step S104, in the case where not finding, picture is cached and preserves the identification information of picture.
It should be noted that the identification information that the identification information for not finding picture in the buffer is corresponding, then the picture is simultaneously
Do not exist in caching, then picture is cached and preserve the identification information of picture.Picture is cached and preserved
After the identification information of picture, if need to load the picture again, the identification information can be found in the buffer, and then directly
Picture corresponding to the identification information is shown, without being loaded again by network from server.
By above-mentioned technological means, the picture in the caching that can enrich constantly, enable the picture more crossed when browsing webpage
It is enough directly to be extracted from caching, accelerate the speed of webpage loading.
Optionally, when being cached picture and preserving identification information, holding time information, wherein, temporal information is
By the time of picture preservation in the buffer.
It should be noted that preserve temporal information corresponding to the time of picture preservation in the buffer, enabling query graph
The time of piece loading, and then, optionally, the picture stored in caching can be ranked up according to the time that picture loads, sieved
The work such as choosing.
Step S105, in the case where finding, picture is obtained from caching and is shown.
It should be noted that the identification information that the identification information for finding picture in the buffer is corresponding, the i.e. picture and depositing
In caching.Picture is obtained from caching to be shown, specially extracts and browse the figure that webpage needs to load from caching
Piece has a picture of same identification information, and the picture extracted in caching, which loaded, needs the picture that loads corresponding in user's webpage
Position.Therefore by above-mentioned technological means, the picture cached can be directly displayed when browsing webpage in webpage, without
By all pictures in webpage all by being loaded in server corresponding to network from webpage, the speed of webpage loading is improved.
The method for caching and processing that the embodiment of the present application provides, determined by obtaining by the unified resource of the picture browsed on webpage
Position symbol URL；According at least to the identification information of URL generation pictures；Search whether mark letter be present in the buffer using identification information
Picture corresponding to breath；In the case where not finding, picture is cached and preserves the identification information of picture；Finding
In the case of, obtain and picture and shown from caching, solve in correlation technique picture to be in accurate judgement webpage
No the problem of being buffered, and then in accurate judgement webpage picture whether buffered effect.
Optionally, above-described embodiment also includes：Temporal information corresponding to picture in caching is traveled through；According to it is current when
Between and temporal information determine the duration that picture preserves in the buffer；It is removed from the cache the picture that duration exceedes first threshold.
It should be noted that due to being the picture in webpage corresponding to the picture in caching, and the picture in webpage makes
After some time, may change or delete, thus cache in saved prolonged picture can be due to webpage
In picture replacing or deletion and it is ineffective, and the picture is stored in caching and generates the waste of storage area,
Therefore, first threshold is set, needs to delete in picture when the overlong time that picture preserves in caching.Set in above-mentioned technological means
First threshold has been put, has then been deleted more than first threshold when the time that picture preserves in caching, therefore pass through above-mentioned technology hand
Section can delete picture that is ineffective in caching and taking storage area.Above-mentioned first threshold can be according to the renewal speed of corresponding website
Spend and determine.
For example, first threshold is arranged to 6 months, the temporal information of the picture A in caching is on May 3rd, 2016,2017
, on September 3, temporal informations to picture in caching traveled through, then the holding time for obtaining picture A is 16 months, more than first
Threshold value 6 months, therefore picture A is deleted.
It is in order to according to temporal information it should be noted that being traveled through to temporal information corresponding to the picture in caching
To delete holding time long picture, and then the storage area of caching is discharged, therefore, optionally, above-mentioned technological means can be only
Performed in the storage area deficiency of caching.Therefore, optionally, in above-described embodiment, the time corresponding to picture in caching is believed
Breath, which carries out traversal, to be included：Obtain remaining memory space in caching；In the case where remaining memory space is less than Second Threshold,
Temporal information corresponding to picture in caching is traveled through, and then, optionally, be more than to the picture of first threshold the holding time
Delete
For example, Second Threshold is arranged to 20%, first threshold is arranged to 6 months, and the temporal information of the picture A in caching is
On May 3rd, 2016, in September in 2017 3 days, the remaining space of caching was less than 20%, then in September in 2017 3 days in caching
The temporal information of picture is traveled through, and the holding time for obtaining picture A is 16 months, more than first threshold 6 months, therefore will figure
Piece A is deleted.
By above-mentioned technological means, to temporal information corresponding to the picture in caching when can be all in cache storage insufficient space
Traveled through, and then the holding time in caching is exceeded to the picture deletion of first threshold.
Optionally, found using identification information in the case of picture corresponding to identification information being present, also united in the buffer
The picture is counted by browsed number.The caching figure being of little use is deleted by browsed number by the picture that comes out
Piece.Optionally, the 3rd threshold value is set, when the number that picture is browsed in caching then judges the picture for seldom less than the 3rd threshold value
Caching picture, is deleted.
Optionally, above-mentioned picture by browsed number be picture within a certain period of time by browsed number, therefore will
The temporal information of picture is combined with number of visits to judge whether picture is to need the picture deleted.For example, preset time is 6
Individual month, the 3rd threshold value was 3 times, and picture A temporal information is on May 3rd, 2016 in caching, and is judged on November 3rd, 2016
Picture A is 2 times on May 3rd, 2016 to the number browsed altogether between 3 days November in 2016, less than the 3rd threshold value 3 times,
Therefore the picture A in caching is deleted.
Optionally, above by number of visits, to delete, the technological means of picture can be only in the storage area of caching in caching
Performed when insufficient, specifically, when the remaining storage area of caching is less than Second Threshold, judge that picture is in one before in caching
Whether the 3rd preset value is less than by number of visits in section preset time, when the number that picture is browsed in caching is less than the 3rd threshold
The caching picture that value then judges the picture seldom to be browsed, is deleted.
For example, preset time is 6 months, the 3rd threshold value is 3 times, Second Threshold 20%, the storage area of caching takes
In September in 2017 18 days more than 80%, then the remaining storage area now cached is less than 20%, therefore counts picture in caching and exist
The number that on March 18 to 2017, on September browsed between 18, in 2017, picture B is obtained 18 days to 2017 March in 2017
September is browsed 1 time between 18 days, therefore can determine whether that picture B is the picture seldom browsed, and picture B is deleted.
The picture seldom browsed in caching can be deleted by above-mentioned technological means, discharge the storage resources of caching.
In another embodiment, when caching picture, URL corresponding to picture and temporal information are preserved；Protect
Leave the URL come and temporal information combines progress big data statistical analysis, it is relatively more to analyze access in a period of time recently
Website, or access the predetermined column of more website；In the case of network idle, above-mentioned website is downloaded in advance or is somebody's turn to do
Picture in the predetermined column in website.
It should be noted that in the case of the network idle stored in order to maintain the remaining storage area of caching, in caching
The quantity a predetermined level is exceeded for the picture downloaded in advance then stops downloading.Optionally, picture size threshold value is set, carried out in advance
When download pictures, judge whether the size of picture to be cached is more than picture size threshold value, and only cache size exceedes threshold
The picture of value.
By above-mentioned technological means, allow the picture in the predetermined column of website that frequentation is asked or website in network idle
In the case of cached in advance, and then improve the access speed of the predetermined column of website that frequentation asks or website.The same time limit
Determine the quantity that picture is downloaded in advance, prevent the picture of buffered in advance from taking excessive cache storage space.There is provided picture size
Threshold value, thus can in the predetermined column of website that only buffered in advance frequentation is asked or website more difficult caching big picture so that subtracting
The fluency of website loading is ensure that while small cache storage space pressure.
It should be noted that can be in such as one group of computer executable instructions the flow of accompanying drawing illustrates the step of
Performed in computer system, although also, show logical order in flow charts, in some cases, can be with not
